The temperature of source of a Carnot engine of efficiency $ 20\% $ when the heat exhausted is at $ 240 \,K $ is

The $ EMF $ of a galvanic cell by coupling two electrodes $ M_{1} \left|M_{1}^{2+}\left(0.1 \, M\right)\right|\left|M_{2}^{2+}\left(0.01\,M\right)\right|M_{2} $ is $ +1.47\,V $ . If the $ E^{\circ} $ value (reduction potential) of $ M_{2} $ electrode is $ 0.9\, V, E^{\circ} $ (reduction potential) value of $ M_{1} $ electrode in volts would be $ \left[Assume \frac{2.303RT\left(T=298\,k\right)}{F}=0.06\right] $

A metallic wire of cross sectional area $ 4 \, mm^{2} $ carries a current of $ 3.2 \, A $ . If $ 5 \times 10^{26} $ charge carriers flow across the wire per unit volume, then their drift velocity in $ m \,s^{-1} $ is

In a potentiometer, auniform potential gradient of $ 0.8 \,V \,m^{-1} $ is maintained across its $ 10 \,m $ wire. The potential difference across two points on the wire located at $ 0 \,m \,65\, cm $ and $ 2 \,m\, 45 \,cm $ is
